Don't know this would be helpful for cMBP users or not, but I found unchecking the "Put hard disks to sleep when possible" function in Energy Saver will avoid the machine going into "deep sleep", especially for cMBP running on SSD.

After unchecking this my cMBP wakes from sleep in just seconds of time, no matter it has slept for 8 hours or so.

Previously, it would simply 'sleep', even overnight, and make in a few seconds.

Now since this update, it seems to hibernate after an hour or so, and then takes up to a minute to fully 'resume' once the lid is opened. I'm not sure why this has changed, or if it is possible to revert to the previous behaviour?

You can push the time after wich it goes into standby to a higher value. You need to calculate the value expressed in seconds.

sudo pmset -a standbydelay <time in seconds>

Example to only go into standby mode after 10 hours:

sudo pmset -a standbydelay 36000

Ive just got my rMBP back from apple today and was wanting to test out this update to see if it reduced the lag as some people are saying it does.

It now looks like im out of luck unless I can get the file from somewhere else?

You're not out of luck .. Apple pulled the update. Because it's broken. Hold onto your stable OSX install for now until a new STABLE update comes out. Scroll above this post to calisurfboy's LIST of issues (not to mention a quick google).. You JUST got your Mac back, unless you have an unhealthy obsession with the Genius Bar, I'd avoid the update.. Which even Apple is trying to stop lol. Is it worth more headaches to solve a few frames dropped here or there on an otherwise stable machine? (Sorry I'm going off the deep end, but it utterly baffled my mind that you'd still want to update after the last 7 pages of this thread).

Like I said in another post.. I edit video day in and out with this macbook .. You couldn't pay me to do the update. Especially with the alleged throttling now happening with that update (see link below).

I did the update a few days back i wanted to update my iphoto and imovie so i left the macbook on charge this is a 15" MBP mid2012 and when i returned and hit the mouse nothing was on so i then pressed the power button and it came on with loading bar just as if the battery had died but it was on charge the whole time...

i need help please any suggestions are welcome

Reset SMC, try it a few times (3) if no joy reset PRAM and then SMC, worked for me

I updated my 15" retina a week or so ago. It's been a horrible update. I've had the keychain problems, as well as severe GPU throttling (I don't have many tasks CPU-bound, so I haven't been able to check that).

If you've downloaded the update and have been thinking of applying it - don't.

The updated 13" MBP w/Retina sure seems like a viable update to me. With its slimmer profile, laminated less reflective display and weight reduction are fairly significant in my view. Fully configured, or nearly fully configured is about the only way I would/may go. Not sure if the SSD 750 upgrade is worth the $500.

I just downloaded the update and just at the end after using up 130 Megabytes of my limited satellite allowance I received an error message and have to start all over. This is not the first time this has happened. I am so tired of Apples slow error prone servers.

I downloaded the update for my 15" rMBP last week and I haven't had any problems with throttling, graphics slow downs or anything else like that. I also haven't had to reset my SMC or PRAM since the update.

I've got the 2.6Ghz 16GB rMBP and I'm running Windows 8 on bootcamp and via Parallels 8. I've been playing The Witcher 2, Deus Ex and Skyrim with no issues whatsoever.
